FAQs

What is the purpose of the MOC process?

The MOC process manages hazards and risks arising from changes to facilities, equipment, operations, procedures, and the organization, by screening and prioritizing proposals, assessing and mitigating risks, and ensuring authorization, standards compliance, and communication/training.

What types of changes does the standard cover?

The standard applies to permanent, temporary, emergency, and organizational changes, with definitions for each type and requirements for how LOBs document and define them.

When is replacement in kind (RIK) excluded from MOC?

Replacement in kind activities are out of scope for the MOC process when the replacement is technically like-for-like, fully conforms to approved specifications, and has no impact on the system. LOBs must still define documented RIK criteria.
